Shrimp fajitas made right on a sheet pan are packed with flavor and couldn’t be easier to prepare. Juicy shrimp, sweet peppers, and red onions roast together with a simple homemade seasoning for a fast dinner that hits the spot.
Why You Need To Make These Oven Shrimp Fajitas
- Quick Cook Time: Shrimp cooks fast, so dinner hits the table in under 30 minutes (including prep time!). That’s a lifesaver on nights when time is tight and everyone’s hungry.
- Versatile: These fajitas are great in warm tortillas, over a bowl of rice, or piled onto a salad. It’s easy to make them your own by adding your favorite accompaniments. My favorite way is in flour tortillas with a dollop of sour cream and a dash of Cholula.
- Perfect for Meal Prep: The seasoned shrimp and veggies hold up well in the fridge, making this a solid choice for prepping ahead and cutting down on weekday cooking stress.
Fajitas are my go-to meal when I need something quick and comforting with minimal prep. I love easy Mexican meals like this, but I don’t want to stand over the stove stirring forever. That’s why I’m such a fan of simple sheet pan dinners like these shrimp fajitas and my Oven Chicken Fajitas.
Ingredients and Substitutions
- Bell peppers – Any color works here. Use a mix for more color or sub with poblano peppers for a little extra heat.
- Red onion – Yellow or white onion works if that’s what you have on hand.
- Olive oil – Any neutral oil, like avocado or vegetable oil can be used instead.
- Shrimp – Fresh or frozen shrimp both work. If using frozen, just thaw completely and pat dry before cooking.
- Lime – Lemon juice will work in a pinch, but lime adds the best flavor.
- Cilantro – If you’re not a fan, skip it or use a little chopped green onion instead.
- Seasoning – Use store-bought seasoning if you prefer.
Mandy’s Top Tip
To keep the shrimp juicy and not overcooked, add them to the sheet pan halfway through the cooking time. This way, the veggies get perfectly roasted and the shrimp stay tender.
Tips for Success
Use a large enough pan – Spread everything out in a single layer so the veggies roast instead of steaming. If they’re too crowded, they’ll get soggy.
Dry the shrimp well – Pat the shrimp dry with paper towels before seasoning. This helps them roast instead of releasing too much water.
Don’t skip the lime – That splash of fresh lime juice at the end brightens up all the flavors and ties everything together.
